documentclass[paper=A4,fontsize=12pt,titlepage]{scrartcl}



usepackage{showframe}



begin{document}

begin{titlepage}

    raggedright

    {

        Some text

    }

    vfill

    {

        begin{minipage}[t][b]{.5textwidth}

            begin{flushleft}

                More text \

                Second\

                Line

            end{flushleft}%

        end{minipage}%

        hfill

        begin{minipage}[t][b]{.5textwidth}

            begin{flushright}

                Additional text\

                fin\

            end{flushright}%

        end{minipage}%

    }

end{titlepage}

end{document}

I want the last line of the left minipage to be vertically aligned at the bottom of the page. The first line of the right minipage should be in line with the first line of the left minipage.

In the MWE the last line overshoots the bottom border. No combination of minipage alignment settings I have tried worked. Wrapping one large minipage around everything did not help either. Either the alignment stays the same as in the MWE or the left inner minipage is aligned perfectly and the right one floats beneath the left.

NEW:

It appears that the number of lines may change and that this example was simply one possible situation. Here is the the content under vfill that you could use which is more flexible:

vfill

{

begin{minipage}[b][t]{textwidth}

    begin{minipage}[t]{.5textwidth}

            More text \

            Second\

            Line\

            Test\

            Test2

    end{minipage}%

    hfill

    begin{minipage}[t]{.5textwidth}

        raggedleft

            Additional text\

            fin

    end{minipage}%

end{minipage}%

}

Which looks like this:

The trick is to wrap them in another minipage where the contents are top-aligned (and it is anchored to its baseline).

If we modify the text to have some assorted font sizes (such as the code below), this overall structure will still work:

vfill

{

begin{minipage}[b][t]{textwidth}

    begin{minipage}[t]{.5textwidth}

            More text \

            Second\

            Line\

            {Huge Test}\

            Test2

    end{minipage}%

    hfill

    begin{minipage}[t]{.5textwidth}

        raggedleft

            Additional text\

            {Large fin}

    end{minipage}%

end{minipage}%

}

ORIGINAL:

To clarify, the first image is what you are seeing, while the second image is what you want, correct?

If I understood you correctly, you can change:

begin{minipage}[t][b]{.5textwidth}

to:

begin{minipage}[b][t]{.5textwidth}

EDIT:

If you want the extra gap under fin, you'll need the strut that @esdd used for his answer. The reason for this is that the blank line at the end (defined by fin\ is ignored). That's why the second image has both Line and fin flush with the bottom. If you add strut (e.g. fin\strut) in addition to the begin{minipage}[b][t]{.5textwidth} change I provided above, you will get this:

You may notice that the left side text is a bit lower than the right side, however. The issue is that strut on the right side uses the maximum vertical space (for the line) whereas the left side doesn't require the maximum (due to the text on the line not having any depth [e.g. the space below baseline that letters like j, g, p, etc. require]). If you want them to be identical, you'll need that strut on the left side also.

The differences will be largely stylistic, depending on which option looks/feels better for you.

You could use a strut in the third line and begin{minipage}[b]{.5textwidth} for both minipages:

documentclass[paper=A4,fontsize=12pt,titlepage]{scrartcl}

    vfill

    {%

      begin{minipage}[b]{.5textwidth}

        raggedright

          More text \

          Second\

          Linestrut

         par

      end{minipage}%

      hfill

      begin{minipage}[b]{.5textwidth}

        raggedleft

        Additional text\

        fin\

        strut

        par

      end{minipage}%

    }
